Max effort with as-cast heads? 🤦♂️
Regardless...that's the WRONG answer. Last thing you want to do is create sudden increase in cross sectional area right where the intake and head come together...which is exactly what you will do. If you're going to move one side of the port over, you better be prepared to move the other side over as well. In this case, since we're just dealing with an as-cast set of heads anyway, best to just leave it alone. The engine will never know the difference.
